3. Installation

Installing the Pressure Tank Unit:

Fixed installation of the Pressure Tank Unit:

Connect the hose to the suction side:

The installation position must be firm and dry, and permit a secure mounting for the pressure tank unit.

➔Install the pump at a safe distance (min. 2 m) from the pump- ing medium.

The pump must be installed in a location with low air humidity and sufficient ventilation in the area of the ventilation slots. It must be at a distance of at least 5 cm from the walls. No dirt contamination (e.g. sand or earth) may be sucked in through the ventilation slots.

The mounting board (e. g. a wooden board) prevents the pressure tank unit slipping.

➔Screw the pressure tank unit to the mounting plate with all four

feet (The use of cap screws is recommended).

Install the pressure tank unit so that there is room to place a suitably sized drainage tray under the drain screw . To allow the unit or system to be drained.

If possible install the unit higher than the surface of the water to be pumped. If this is not possible, install a vacuum-resistant shut-off device between the unit and the suction hose, for example for cleaning the integrated filter.

If the pressure tank unit is being permanently installed indoors for domestic water supply, the Pressure Tank Unit should not be connected to the domestic water pipework with rigid pipes but with flexible hoses, to reduce noise and to avoid damage to the pressure switch due to vibration.

If the system is being installed permanently, please fit suitable shut-off devices on both the intake and delivery sides. This is important e.g. for maintenance and cleaning work or if the system is being shut down.

The connection pieces on the intake and delivery sides must

only be tightened by hand.

Do not use any water hose snap connection system components on the intake side. A vacuum-tight suction hose must be used e.g.

•GARDENA Suction Hose Art. no. 1411

•GARDENA borehole Suction Hose Art. no.1729.

To reduce the pump repriming time, we recommend:

•using a suction hose with backflow preventer, which prevents the suction hose emptying automatically when the Pressure Tank Unit is switched off.

•If the suction heights are high, use a suction hose with a small diameter.

1. Connect vacuum-tight suction hose via a connection piece (e.g. Art. no. 1723/1724) to the connection on the intake side and screw in place so that it is airtight.

2. For suction heights exceeding 4 m also secure the suction hose (e.g. by fastening it to a wooden post).

This relieves the pump of the weight of the suction hose.

If very fine dirt is present, we recommend the use of a GARDENA pump preliminary filter art. 1730/1731 in addition to the integrated filter.
